I have a '66 Mustang 6cyl automatic with manual brakes that I'm in the process of converting to a V8 5spd. My question is can I change the brake pedal and add a clutch pedal to the existing pedal support or do I need to swap the whole pedal assembly from a manual trans car. Also is a 6cyl Z-bar and brackets the same as a V8 or is the Z-bar itself different for a 6cyl car.

I did do a search for these questions but was unable to find an answer so I thought I'd just ask.

: The carrier assembly is the same. What you will need is the spring, a hook piece that bolts on the back of the carrier, and a rebound bumper for the clutch pedal. These are only found on a standard trans carrier. Many standard set ups have long since blown out the bushings, so, you are better to use the carrier from the automatic, and just trasnsfer over the parts.

The Z bar is different, and 65 and 66 Z bars are different from each other on both the 6 and 8 cyl cars. The brackets are the same. If you need more help, or some pictures, let me know.

You can use the existing pedal support, but you will need several pieces from a clutch pedal support to swap over (pedals, clutch pedal stop, spring, spring brackets, etc.). I suggest you locate a complete pedal support from a stick shift car and use the parts from it on your existing automatic support. Almost all the used manual pedal supports I've seen are tweaked from the forces involved in working the archaic Mustang clutch linkage. Your automatic one is probably in good shape.

Remember to get new pedal bushings and the little Delrin clips to insulate the ends of the big spring.

As for the Z-bar, I believe they are the same for 6 cyl and V8 cars, and the only oddball was for the K codes. There was a difference in the '65 and '66 versions, though, so you will need to get the one that matches your clutch equalizer rod.

It's been awhile since I did this conversion, so I hope I'm getting all this right. If anybody knows differently, please chime in . . .

I did the conversion utilizing my automatic pedal support. I fabricated the bracket to connect the assist/return spring out of 1/8" thick flat stock. No big deal. Bumber, I didn't need no stinking bumper. It works fine without one. I fabricated a clutch cable set up, so I avoided the whole z-bar issue.

Feel free to P.M. me if you need specifics on what I fabricated.
